Constructor Detail

Arc

Arc(MultiresolutionMesh mt,
    int id,
    ByteBuffer buffer,
    int baseOffset)

Creates a new Arc instance.

Parameters:

mt - MultiresolutionMesh instance that the arc is part of

id - id of the arc

buffer - buffer that contains the binary representation of the arc

baseOffset - offset in the buffer

Method Detail

store

public static void store(ByteBuffer target,
                         int sourceNode,
                         int destinationNode,
                         int lowestPatch,
                         int highestPatch,
                         int nextArcWithSameDestination,
                         float geometricError)

Stores the information of an Arc in the given ByteBuffer.

Parameters:

target - buffer where the binary representation is written to

sourceNode - id of the source node of the arc

destinationNode - id of the destination node of the arc

lowestPatch - lowest patch id in the label of the arc

highestPatch - highest patch id in the label of the arc

nextArcWithSameDestination - id of the next arc with the same destination node (-1 if there is none)

geometricError - geometric error

getFragments

public MeshFragment[] getFragments()

Returns the fragments associated with this arc.

Returns:

the fragments associated

interferes

public boolean interferes(ViewFrustum roi,
                          float zScale)

Determines if this arc interferes with the given Geometry.

Parameters:

roi - geometry that is tested for interference

zScale - scaling factor applied to z values of the mesh geometry (and bounding boxes)

Returns:

true, if the arc interferes with the geometry, false otherwise

getBBox

public float[][] getBBox()

Returns the bounding box of the region that this arc represents.

Returns:

the bounding box
